Updating ad

Hi, does anyone know how to update an existing ad? I have decided to extend my Dallas visit, but my ad was already up. I thought I read somewhere to PM the mods for that forum, but I have not heard back. I sent another PM to another set this morning, just in case that is the correct way.

Thanks,
HoLLy

As far as I know, after an hour past posting you cannot edit it yourself so RTM the post so a mod can edit it is your only choice. Assuming they are willing and have time to do it.
