Ignore option?

Not sure if it is an option with this forums software, but as there is meant to be an upgrade perhaps the tech people would consider adding an ignore option to the forum, which allows members to not to see posts from certain individuals for whatever reason.  While it may seem like an unpleasent option, I do think it would be a good thing to add and I myself have used such an option on another forum when another member was proving to be very irritating and doing my head in.  It makes things much easier in such circumstances and can avoid causing aggro.
