Just an FYI...I am not the administrator.
Web tech issues are largely beyond my areas of expertise, and I've not experienced any of the problems mentioned in this thread, thus far. While the hosting service has had occasional glitches over the years, they have been few and far between. And, I'm unaware of any issues with vbulletin at present. Based on what has been posted thus far, it sounds like a browser issue at the user end of the chain. I'd suggest clearing the cache, reviewing your privacy & security settings and white-listing lilhonda.com. That should take care of it. I do know that this site uses cookies to function properly and some security settings can interfere...effectively erasing your presence during a session.
The only issue I've encountered is being logged-out quickly, for "inactivity", which can include composing a post. Even that's intermittent.
If you include a quote, then attempt to review your post before entering any new text you will then get the "must enter at least..." prompt.
On the admin control panel side, "under the hood", there's one huge, sprawling, program with more controls, bells & whistles than you can imagine and it's all too easy to inadvertently change something...then end up scratching your head when the result manifests.
I suspect that the OP is where certain options, such as allowing emoticons, are set for the entire thread. In this instance, I'm referring to option #4 under "miscellaneous options".
