Simple contact form easy to use: any suggestion?

Hi,

I'm looking for a simple contact form, compatible with multisite and easy to use for non-skilled end-users in the network. You have a contact widget in your plugins but I'm looking for something that could be integrated into a page.

Two plugins retained my attention:

I think I will choose Grunion. Do you have any opinion or suggestion?

And finally, is WPMUDEV planning to offer a similar plugin (which is a basic and very common feature) in the future? Would be nice!

Thanks for replies!

Laurent
