I have a few questions…
why not use the standard wordpress editor for desctiptions of events? It seems that your editor adds a ton of extra html code that I have to manually strip out. However, then it seems to add it back in anyways. The worst offender is <li> tags. The editor wants to wrap the text inside of that in <p> tags, causing dispaly issues.
In the gallery upload, could you make this a true gallery selection, but allowing to upload more than one image at a time to it?
