It's not the end of the world - rather a curiosity.
I am running 6.6.0 (with no intention to upgrade until the new software). I've searched this site and the update notes and did not find any reference to this.
If I post the phrase "avatar -" (ie avatar space dash), the server returns 403 permission denied (to main script). If I add an extra space then it will post, but will display as a single space. if I take the space out it works fine too.
I can't see too many people ever encountering this problem, so it is probably low, low, low priority, but I am just curious if there are other such forbidden phrases. It took me almost half an hour to work out what was wrong (incl making sure all the permissiosn were set right on the server) but other users may not be as persistent <img src="https://www.ubbcentral.com/boards/images/graemlins/wink.gif" alt="" />
