I'd received a private message yesterday and replied. However, now I'm getting amessage telling me that I can't send/receive private messages. How and why has this occured?

When you are in the Private Messages section, there will be a "Sent" link that will list all the Private Messages which you have sent.  I assume that you replied to my PM about the Zion factions on Recursion, but I can't receive or reply right now because for some reason (probably related to the Bluepill rank April Fool's Joke) the board is telling me that I don't have privileges for Private Messages.  Virrago, help!  I'll post the problem in a new thread for more visibility.

Try deleting your browsers cookies... you could have a bad cache

Well it wasn't specifically a cookie issue, but it's working again.  I use and recommend a free utility called CCleaner.  It cleans out cookies, temporary internet and Windows files, as well as a very good (safe) Registry Cleaner.
