dunno if it could be done, but a few times when i've been working on a long/complicated post maybe over a few days/weeks i've found i have to use something like word and then copy and paste it all over and re format it and stuff. would be nice if when your making posts you could have a 'save to drafts' option and it'd just keep it for you somewhere you could go back in and update it and stuff before posting. dunno if it's possible/practical or useful but i just thought i'd throw the idea out there!
there's the notepad bit i use sometimes, but it's not got smily's or the formatting options and i end up opening up a new topic, typing it all in there then copying and pasting it across cos i can never remember all the code.
anyway it's not a major problem, just a bit annoying!
