Challenges

I'm sorry if this is the wrong forum for this but I couldn't think of where else to put it.

On the personal information page there are two radio buttons where you can switch from automatically accepting a challenge or automatically declining a challenge.

My problem is that the only internet connection I have is via the computer in my local (and part-time) library. Because of this, I cannot reliably play at any speed greater than 15 days per move.

I'm am happy to accept all challenges as long as I can meet that time control. I have subsequently set the radio button to decline all challenges to save people from challenging me unnecesarily but it would be nice to have the option of attaching conditions to the accept/decline options to cover my sort of situation.

Just an idea...

Thanks.
