After the grand move to the new server, we are still taking care of the aftermath of the upgrade, smoothing things out and such. You may find a few small changes here and there, that we have added after the upgrade.
One of the recent smaller upgrades is the ability to change username while posting. Many people have more than one username, and when posting, it's handy when you can switch from one username to another easily. Therefore, you will now find a link right next to your username, when making a post, that says "Click here to change Username". It will allow you to log in to another username you have, and will then bring you back to the post you were making.
Note that this does not apply to the "Quick Post" box at the bottom of the posts. That one can only be used if you intend to post with the same username you're logged in with at that moment.
More such smaller upgrades may yet take place, as we stumble across practical problems. We are also still in the process of adjusting member levels and access for the captains and admirals and such. If yours is not adjusted yet, please do let us know.
