If I edit my Area 51 proposal and I exceed the limit of chars, I have to wait 30 seconds to try again.
For example, I edited my Gardening Proposal to add landscaping. When I was done I saved and was told I was over the 255 char limit. So I deleted a sentence and saved again. It then told me that I can only edit a post once every 30 seconds.
But I had not really edited my post. At least this should be changed to say you can only submit an edit every 30 seconds.
