Hey, i muted your post because it didn't follow our community guidelines as it had no photography. I will help guide you. Some of the error messages you are getting are probably due to Resource Credit issues. Hive uses resource credits to limit the ability to interact with the blockchain for accounts with little to no Hive Power (powered up or staked Hive) mostly to limit bot activities.
This won't be an issue once you get a bit of your Hive staked and Powered Up. I would recommend not making any posts or comments yet. I would also not upvote anything yet. If you are using PEAKD you can hover over the stats bubble and it will tell you what your HivePower is and your Resource Credit level is. It shows as of now you will be fully recharged in resource credits in two days. You can use this time to read up on the posts below and work up a nice intro post.
The first thing i would do is get yourself a profile picture and a cover image for your account. Then, i would recommend making yourself an introduction post telling Hive who you are. You can use the tags #introduceyourself and #introducemyself and post into the OCD Community if you want.
This will help you get a nice start. I also made two posts to help explain Hive and how things work here. Inside these posts i have links for how to format posts and a bunch of other useful information.
To help support your success and to help you from making any mistakes here on the platform... i wanted to share two posts i made to help newer users do well here on Hive.
Please check those out when you get some time and make sure NOT to do the things in there it warns against doing. I think this will increase your chances of support moving forward and accelerate your growth as well!
I hope this helps you out a bit and sorry to throw so much at you in one go. Don't respond to this comment so you can save your Resource Credits for your Intro post. Definitely read those two posts and try to understand them before you attempt your intro. The comment sections have a lot of questions and answers in there as well.
