This isn't a SMW hacking issue - moved to SQ&B.
As far as I'm aware, there's no current issues with the site (or at least, nothing else has been noticec/reported). This could be an issue on your end.
Not sure what you mean by "and i also need a post for the "edit profile"" - your "bio" area is somewhere you can write about yourself if that's what you mean? Other than that, you'll need to explain further. turns out you actually need to make a post to edit certain parts of your profile now (learnt something new today!) you've made that post now by making this thread so you can edit your profile now.
