That's a shame.
Perhaps there is room for a small compromise? How about at least enabling auto-complete which is currently disabled (input autocomplete="off")? That would take away some of the annoyance!
Also, if one logs in to the forum and subsequently decides to visit his 'MyWebAssist User Profile (mywebassist/userprofile.php) he/she has to log in again - even if he/she is still logged in at the forum! Could the user session persist at least throughout the WebAssist site? I could recommend a good forum to help with this if required.
