I'm not in a position to know for sure why you were rejected, but it may have been due to applying to a spammy category. You may want to apply to one that's less of a spam magnent. <img src="/images/icons/smile.gif" alt="" />
As far as content goes, I think I'll leave that for an editor more experienced in that area. <img src="/images/icons/smile.gif" alt="" />
But it is acceptable to have both a listing in Regional, and a listing in the appropriate topical cat.
It looks to still be in the unreviewed queue. <img src="/images/icons/smile.gif" alt="" />
How long it takes to get listed depends on the category, and the available editors in that area. Someone will get around to reviewing it, sooner or later. <img src="/images/icons/smile.gif" alt="" />
Unfortunately, as the RDF dump has been crashing, and staff have as yet been unable to fix the problem, I don't know when it will be fixed. Staff are working on it, though, and hopefully it will be fixed soon.
