Basically involves me trying edits and passing on errors with screenshots and timestamps, them changing some rules every time. Time differences are making it a slow process with one or two changes a day.
Now at the stage of involvement from hosting in trying to replicate issues as nothing technically wrong with site itself (edits by me under 'Recent Changes' includes hosts working on it with my login). There's been some improvement as can now add a limited number of characters rather than none. Hopefully they'll be able to narrow down the exact problem soon.
I've been reluctant to update because until resolved it isn't, but appreciate everyone's frustrated - so for information.
This sounds like great news! Please do post updates, even if it doesn't seem like there is much to say, even if it's only "we continue to work on the issues." Updates of little or no progress are still better than no updates at all (Cryptsy, anyone?).
