Only 3 licenses are listed - Apache, GPL and LGPL… I like the CC stuff (Creative Commons — Attribution-NonCommercial-ShareAlike 3.0 Unported — CC BY-NC-SA 3.0 in particular). It’d be good if you listed more or had an option for “I’ll put the license in the code”.
Image required? I’m adding a video and don’t have a picture…
If possible, it’d be good to not allow more than 50 characters in the title instead of allowing more then doing an error on Submit. (edit: and only 50 chars?? I’m far too chatty for that limit!)
If you mess up the form, you have to type most of it in again…
It’d be real nice to not have to do that.
The link to the Tags page (http://www.tinyclr.com/tags/) is not found and should open a new tag/browser, not move the existing one - again with the having to type all the stuff in again. 
edit: and… when it did take the Submit, it just said “new website coming soon!” which almost made me scream… It added it anyway. Just messing with me, I guess.
Also, it looks like the code display uses 8 spaces for literal tabs. I think the msdev default is 4, which looks a lot nicer. IMO.
CC is not a software license. It is suited for hardware design.
I will forward other suggestions to the experts
The link to tags has been fixed. It will now open in a new window. I also increased the title length to 100 characters (the input box will not go over that limit).
Wow. Don’t I feel like an idiot? They don’t make that overly clear unless you look for it…
That was fast! Thanks, Gus & Josh!
Last one, though I’m still tempted to complain (to them, not to GHI) about CC not being recommended for software, the code viewer for example code escapes < and > characters in comments… I’ve got a section in example code and it comes out as /// . The one that displays a .cs file from the zip does display these correctly.
edit: arg… forums being helpful and not showing the problem… the shows up as something like & lt ; summary & gt ;
I tried to update the license on my submittals, but when I clicked the “Modify” link it jumped back to the Browse page and displayed a big red message saying:
! Unable to process your request.
@ Josh
Wow you’re fast!
Sorry, but one more minor issue… it won’t let me upate unless I upload a Primary image. Even though this field is not marked as required.
Same here, went to update but it is asking me for an image! There is already an image.
