For the record, Plesk Forums are generally oriented towards a community-based approach to support issues. The forums are not really officially support channels in the same sense as a Plesk support ticket which specifically focuses on your unique setup while the forums tend to be supported by volunteer knowledge although it's nice that there are some Plesky folks such as Igor who are active threads. Sometimes scenarios need a second look from a Plesk representative and in the context of the forum, you may not get an answer or the right answer as quickly as you might from Plesk directly. For the most part, the snarky or condescending attitudes in responses may not necessarily be intentional so don't let it be off-putting. Plesk and cPanel are both mature products with different strengths and communities supporting them (such as this one) beyond the official support channel.
