Sign up was very fast.
Everything is created to be easy used, and so it was, but when i created account and also link for that account, it do not ask to give a title, and automatically set "untitled". Tried to find and change it, but at start without success. Later managed to change it under "preferences". Created also post about Archive systems, and give it a title, than it was at the start offered option to give a title, and was very easy to create it. Here you can check the result of it
Also entered different tags for my post. And my idea was to test, how fast it can be found on tumblr by searching these keywords. Waited till 30min, but still system do not find it.
Will try later again :)
Link to check, when post will be found by tags
