Hello danielbliss, you really want to be careful about tiny URL commenters. The big problem with them is you don't really know where they are going to go. The individual is being pretty clever below, https://steemd.com/ is a real page, and really is related to steem, the tiny URL he uses, I am not so sure about, it does not say where it goes, or what it is about. Also his reputation is only 15, now that in itself does not truly indicate foul play, but it is a warning sign that all is not as it seems, especially when tiny URL's are used. Enough said, just do not give out your password to any off steemit site, unless you are 100% sure it is steemit related.
Communities, there are a lot of them. Since you are from Canada you might want to look into #teamcanada tag .
Me I work with a group of individuals for @newbieresteemday, and @newbiegames, we try to help people get a leg up on steemit by providing assistance where we can. I'm sort of a go out say high vote and comment kind of guy. I know nothing of or about the crypto world, other than Steem is a cryptocurrency. Some of our members know a bit about it though. We also have a Discord chatroom, so let me know if your interested in it, or just look on any Post that has Newbieresteemday in the title. Well that's about it, once again welcome to steemit.
