Great @Betterlatethan! Following you.
Now more tips. @margarethall as far as I could establish, there’s no way to attach pictures into the post but you can change cover picture, this is one which is at the top of your post (where the title of the post is set). On the top right corner there’s a button saying “Upload Imatge” and if you click on it you’re able to choose the photo from your computer and upload it. It appears as a darkened banner carring title of your post on, but it also apears as the thumbnail of your post which is much better than having the default one so the post stands a bit out from the other posts this way.
I strongly believe the things will improve and more features will be added.
You can also update your profile with uploading profile picture, telling the world a bit more about yourself and as much as I see there will be possibility of listing your interests so people would easily find other people of the same or similar interests.
I also uploaded two posts (which were already published on my old blogger blogs but no harm to be added on Journaly too), one in German and one in Spanish. Both are very short as I really didn’t have much of idea what to write really. I just knew I have to try to write something and that was it: 
Writing or editing the text in the post you can only use those standard things like bold, italic, strike out etc and you can add numbered or buletin list and I believe this is approximately all. apart from seting text as a header also. As much as I can remember, you can’t post links of any kind in the posts for now either. But what you can do, you can add links to your Facebook profile, YouTube channel and a link to one of your sites (if you have any) directly into your profile so the visitors can click on the links which take you straight to the desired destination. The links open in separate tab so no worries the visitor would be carried away from your Journaly profile though. 
Now, this is really all for now.
Good luck with posting.
PS WOW! Only now I’ve seen that people can comment your text with the corrections exactly on the wrong expressions and I’ve got some of them in both - Spanish and German text - which is prety cool. You can correct the text if you wish or just learn out of the corrections/comments you get on the text. This is separated feature from the comments you can post below the posts so expect someone will correct your texts and this way you’ll be able to learn rules, words and other things too!
Gwych!
