Just leaving this here for anyone who may be struggling with Resource Credit issues:
Hive account@giftgiver will give you a free delegation just by heading to their website https://giftgiver.site and entering your username.

It's a really nice website for if you are in a pickle and cannot send a message or send a transfer due to a lack of RC available to you.

Besides that, good post I wish I knew more about RC when I first started with Steem.
