Penniloop has multiple ways of helping you meet new people in your communites. Following users is easy, just click on their profile and click "follow". You must have a Penniloop account (and be logged in) to use this.
To find people you may know already, use the profiles page to search their username, business name, or city location. To meet people you may things in common with (like cats, music, miltary, etc.) search the topic page (example animals, environment, seniors). When you see a post you like in that category or interest, click on the title.
The post details will show who made it. Click on their username or profile view buttons. You'll be redirected to their profile where you can see other posts they have made, their location, who they follow, and the things they are interested in.
If they allow emails you will see email buttons on the details page as well on their profile. If no email option is present then following them will let you know you're interested. You can also "favorite" a post of theirs and they wil get an alert when they log back in.
If the person follows you back, make sure your email option is not hidden. Their profile may include Facebook and other social media links which they have made publicly available.
