Hi @tobatunaornot, sorry for the late reply, we only now saw your comment!

Our EasyEditor has some special features that are not available on other frontends and in some cases there can be incompatibilities like the spaces you experienced. If having your post look great on TravelFeed is most important to you, we recommend using EasyEditor (that also has cool features such as image galleries or the table of contents) and making edits through TravelFeed only, but if you want full compatibility with Hive/Steem, you can switch to the Markdown/HTML Editor which is the same as on other Hive/Steem frontends.

Hive and Steem both work with a resource credit system - if you don't have enough available resource credits, you can't post - this is a problem that many new accounts have since you start out with very few resource credits and accumulate more resource credits as you earn more Hive power/Steem power. This was the reason why posting to Hive failed for you. We have delegated you 30 HP so your next posts should go through :)
