If krill would be worth more, probably yes.

Not a cash table suggestion, but a bad beat jackpot suggestion:
I've seen at some casinos in the past the 72o Bad Beat Jackpot. It would be nice to have one on Swc.
How it would work (as I see it):
1% of rake goes into jackpot
If 72o wins against trips or better, winner and loser split the jackpot ( 40%-40% or something similar, didn't calculate odds) rest 20% seeds the next jackpot.
This jackpot would be hit faster than actual jackpot, I think.

Stream "Seth won Seth, street won street, AA lost J8" . Win millions of chips.
My humble suggestion.

There is a gap of 2 hours minimum between tournaments during European day time.Consider adding some small tournaments to fill those gaps. Also, there are gaps between buyins, you have 10 chips freerolls, then Tiny Turbo with a buyin of 100, another one with a buyin of 250 and all the rest is above 1k chips buyin. If you would fill the gaps mentioned above with small tournaments like 50 to 500 chips buyin, it would be great.

I know few things about email marketing, sending emails to your customers, which gave you their email address when signing up, is NOT considered "unsolicited email". If you comply with CAN SPAM rules (first link), then
as defined in second link.
I'd suggest you to read more about this and reconsider the definition of "unsolicited emails". With all due respect to privacy.

Regarding tournaments, I'd suggest to open as many as you can, of all sorts. After a while, should be easy to decide which are played more and worth improving and which ones should be killed without regret, because aren't played. Voila, listening to customers.

After solving your hosting issues, you might want to solve your marketing issues and bring up that affiliate panel with referral links. You did a great job with the software, I don't care what is said in trollbox about some minor bug with some text that can't be seen or time format that's not working. These are not issues.
Your player base almost doubled since 3.0 launch, it's foolish not to build momentum and 3x or 4x the player base, just by offering them tournaments to play(see bojax's post above), promos like some Big Sunday Freeroll or Krillrolls (even with small prizes) .You could bring back The Big Btc, even with smaller gtd.
You should consider emailing all players about relaunch, there are people who might forgot about SWC.Also emailing about updates and such wouldn't hurt.
There are ways to grow, I won't say more.
You say you wait for higher average traffic. Traffic doesn't play poker nor deposits on your site. Players do. And players want to play, if you don't offer them tables they want to play, they won't spend money on SWC. Easy.
Also, you say you like your site's design. It's not about you, you may as well keep the site private and admire your work at home. Should listen to people's suggestions, even if you don't change anything from a single opinion. Listening to your customers could make a huge difference for your business.
Well..rant over, I'm almost sure my message will go ignored, but hope dies last.

There is an Android app called Forum Talker, that works just for reading Bitcointalk (and any other forums). I didn't manage to reply from this app, probably because of login recaptcha, however for reading works good.
