Info on what the SLA is charging -- appears to be $750 per firm plus you pay for the conferences which seem to be $750 for each attendee. Aside from links on their web site and press releases it does not seem like they have another method of communication though I haven't looked at that closely.
This seems like a direct competitor to the IT Alliance though several key members are missing such as Net@Work
