Welcome! I'm rather new to the community here and Goldcoin as well, but I'm not new to cryptocurrencies.
I'd be more than happy to help you continue growing your wallet, but I'd be curious to here on where you're looking to expand.
If you're looking for easier ways to purchase altcoins, such as Goldcoin, I really recommend Cryptsy. Here's a link:
https://www.cryptsy.com/users/register?refid=315291I find that exchange to have the widest assortment of coins to trade in and although the verification process is sort of time consuming, it makes it easy to purchase a variety of currency using money from a bank account.
If you're looking to mine coins, which is a hobby I'm just starting to get back into, you're probably going to have a bit more research to do, but I'd be happy to help you out if that's a direction you're looking to go.
