That's the option I ended up using, It's a slightly different requirement, so I can see it being low priority on the "would be nice" list.

Hello. I ran across a site (the US Postal Service!) that requires that no consecutive characters be repeated. That is, "abababab" would be acceptable, but "aababab" would not because there is an a followed by an a. Is there a way to put that on the (admittedly low priority) feature list? I can give a more formal definition if needed.
