Hi,
this may be a isolated deal or it may be something to watch for, i dont know yet as this has happened once so far.
I have not deleted anyone from my members, i just finished xfering my membership over from another script and today i noticed that someone had posted a question and their name was deleted user.
I did click on their name and i got a bunch of template/php code on the page so i refreshed, i should have copied that code sorry. They were in the question widget but not on the memberlist.
Anyway i did delete that user but this was very strange. Lets hope this is just on of those once in a lifetime deals.
ps i love the plugin... :)
