I haven't really gotten nitty-gritty with the customizing yet, though I do plan on experimenting via localhost. For now a few template edits and css changes have worked well. We do plan on having some custom addons developed to fit the forum and community (i.e. dogecoin/bitcoin trader, vault, etc) but that's going to take even more crowdfunding.
Anyways, if you're into cryptocurrencies (dogecoin in particular) MyDoges.org is a great place to start getting in with the community. Our staff team work extremely hard to verify that each seller and buyer have a good reputation wherever they are: reddit, doges.org, and other sources. Our whole goal when we started MyDoges was to create a place to communicate with other 'Shibes' without having to worry about losing your money via scams and such. So far we have succeeded.
Suggestions/Feedback would be greatly appreciated!
