Has this happened to anybody else?

It happens pretty often to me too, mainly because I use mostly my tablet. That's because the site let you in for max. 30 minutes, then you are logged out due inactivity. Writing something is considered inactivity, as no page loads during writing a post. So, it took you more than 30 minutes to write that message, and the site automatically logged you out.S

Sometimes, for precaution, I copy everything, and if the incident happens, I just paste it over again.

Hopefully this helps you. :)

Thanks for the help, DinoSteve :) That's a pretty stupid system.

@ Linkzilla, if you have visited Scified you will have noticed the option to "stay logged in", atm this is in test phase but once all the bugs are ironed out we will be rolling out this feature across the whole network.

Please bare in mind that all of our sites are custom-made, from the ground since prometheus-movie com, as such, while we have ultimate control to implement whatever features we want into the forums, each feature has to be coded in, from scratch by our Admin and Coder Chris Picard.

While we understand your frustration, we do ask for your patience and consideration - Thanks.

If you are taking longer than 20 minutes to write and post; you can open a new window and refresh the site there, so you will be still logged,(I recomend you dont use Privacy mode) and is easy  copy your thread before post itm  to make it sure you are no going to lose it, I think is the way used by most of us, (use CTRL C with the keyboard).
