Browse for photographers in your area and leave comments on images you like, send a friend request or message. Start a list of photographer's photos that you think are top notch for photographers in your area. This can become something of a Rolodex. Make sure that you select the Advanced Options and select an appropriate Logged in within:. I typically use 30 days, but you may want people who respond faster. Otherwise you will get photographers who haven't logged in in over a year. There are a lot of inactive accounts.
Make an announcemnet. Look on the front page for members offering comments for comments, and comment on their photos. Also make an announcement yourself.
Post a bulletin by going to My stuff > bulletins. Friends can see the bulletins you post.
Be active in the forums, but avoid trolls who start threads just to watch the ensuing flame war. Avoid threads that beat the 
over GWC's, flakes, escorts, ..., etc. Make positive constructive comments. Whenever you get published, add some new photos, or accomplish anything in general, post an announcement in the Accomplishments, Achievements and High Fives forum. When people see your forum post the first thing they see is your avatar. It has to be interesting enough for them to want to click on it and look at your portfolio.
Share your other accounts on the Social Media User Name Sharing Thread.
Rinse and repeat.
Good luck in your search!
