possible to delete discussions you started?

I have yet to find a way to delete discussions and I don't think there is one. Old discussions probably get automatically deleted after having had no activity for a long period of time. The reason for not having a delete feature is to probably prevent people abusing it since if there are a lot of posts in a discussion that might disagree with what you say myLot wants to support an open community and not allow you to delete your own discussion even if it does not support your own point of view.

I think it's better to contact MyLot administration. However, it may take a day or such to your discussion to be deleted.
