Looking to trial gsa ser, and just started reading about gsa serengines- third party add on for gsa. can I use that to create and update Web 2.0 properties? im thinking of building a set of Web 2.0 properties and updating them constantly, using them as tier 1 and them running a standard gsa campaign to those properties, for tier 2/3. will that work? also, will gsa provide content or should I use something like word ai?
