These aren't the collective ideas of the moot, but should be considered as a way of reforming English spelling. I'll be listing digraphs, letters, or general spellings, and saying what should be done to them in my opinion.
C for S[]
When C is used for S, ſ or ß could be used. I'm unsure of the specifics. S could also just be used.
-le / -re[]
Influenced by French, should just be -el and -er.
Silent E[]
Always pronounced Uh, unless the etymology of the word didn't have a silent E, in which case, the silent E is removed.
Sh[]
This digraph was made on influence of the French digraph Ch. It should become what it was before the French influence, sc.
Ch[]
This digraph was made on influence of the aforesaid French digraph, which represents the Sh sound. It should become either just c, which would be confusing, or with a tsc, on pattern of German tsch but using sc instead of sch.
Th[]
This digraph was made on pattern of Sh and Ch, and should be made þ or ð. I suggest Þ for unvoiced and Ð for voiced as it is in standard Icelandic.
Gh[]
Yet again, made on pattern of Sh and Ch. It should either not be shown, as it is no longer pronounced, or be brought back pronounced and represented by ȝ. If chosen to be brought back rather than forgotten, it should be the softer /x/, not /χ/, as that is how it is in every Scandenavian language and Icelandic. Only central Germanic languages use the /χ/. Otherwise, just an F or nothing.
Ph / Rh[]
Just P and R.
Wh[]
Again on pattern of all of the (consonant)-H digraphs. It should either become H or W, depending on dialect. Some dialects occasionally say H but most say W.
Ow / Ou[]
When pronounced like Au rather than Oo, eo from Old English, æw phonetically, au / aw from German.
Qu[]
From French Qu, should become Cw from Old English.
J / Dge[]
Both from French influence, J from J and Dge from the soft G. It should become either Cg or Dsc depending on preference, Cg going with just C and Dsc going with Tsc. Cg is from Old English while Dsc is from German Dsc.
V / Z[]
Both from French influence causing consonants to be voiced rather than unvoiced. They either should be reverted back to F and S, and be unvoiced again, or represented by the norse letter Ꝩ for V. Z has no germanic letter, and is still represented by S in German.
Y[]
Y should be J, on pattern of all other Germanic languages.
W?[]
W was made on the disliking of Ƿƿ, a rune which became a letter in Old ENglish, from UU. W has since made its way into Polish, German, Dutch, and others, so it's preference.
A vowels[]
Short A, Ah, should be a.
Long A, Ay, could be ei from all Scandenavian languages or ej if at the end of a word. Or, ai and aj, although many examples of ai and aj come from French sources. Some come from English examples of OE æȝ, however. It also could be ea from Middle English. I suggest ea personally, since it is showing it is an A made closer to an E.
Umlaut A, A in Cat, should be æ from Old English and Danish (although Danish generally makes this more of an E sound).
E vowels[]
Short E, Eh, should be ee.
Long E, Ee, should be ie from Middle English, some Modern English, Dutch, and German.
I vowels[]
Short I, Ih, should be i.
Long I, Igh, should be ei if ei is not chosen to represent ay, if so ij from Dutch will do, maybe even being better than ei. Aj from a few German examples could work, although obscure.
O vowels[]
Short O, O in Not, should be o.
Long O, O in Rope, should be oo, on pattern of Dutch and Middle English.
Au/aw, in Lawyer, should be oa, as oa represented the au sound in words of Anglish origin in Middle English.
U vowels[]
Short U, in Run, should be e. Short E was an "uh" sound in Middle English.
Long "U", in Boot, should be u, as in German, Dutch, and Old English.
Long U, in Sue, should be ew, as in English. If you're confused, in many dialects, Boot has an "oo" sound and Sue is more of an "iw" sound.
Other Long U, in Use, should be ju, spelled phonetically, or simply ew for simplicity. It also could be ui.
"U", as in Put, should be ui, made up to show it is basically a mix of the short U and short I.
Exceptions[]
All exceptions should be spelled phonetically and not etymologically. Etymology in spelling has screwed things up for English many times in the past ("ache" for "ake" for example, Ache was a "speak/speech" situation before being mistaken for being a Greek loanword). Would becomes Wuid or Ƿuid, for example.
