I know you didn't ask for feedback on your site - but for SEO purposes - I'd recommend putting the search box + a few recommended events on the front page.

Additionally - I'd mess with the title tags to be more descriptive/targeted like for the home page "Buy & Sell Tickets Online - TicketTrunk" or for the events page "Tickets for events in Ontario" (same with search result pages)

Lastly, multiple press releases being released one after the other (in my opinion - I don't know for sure) will likely be picked up/flagged as trying to game Google & will have a negative effect.

I try to space mine out for important things like launch, system improvements, milestones & event sponsorship.

with that said - I recommend ereleases.com very good syndication (onto high quality sites like Forbes, etc)
