Home page:
- The log-in/register container is too big, up to the point it hides the website's name.
- My browser is set with a zoom of 125%. Reducing it to 100% I discovered there is a menu bar on the left. (I'm surely not the only one with a zoom set over 100%)
- The homepage should be more descriptive of what the website is about (no need a 2500 words article)
Just minor things concerning the design but visitors only give a few seconds to check if the website is interesting to them, so you only have a few seconds to convince
Internal pages:
- When I visit a user's profile (in example members/thisal/) I can't see the update posted despite there is one. Even clicking on the "Activity" tab where I guess it should be located?
To compare with Twitter, when you visit a profile you can see the tweets posted directly on the URL profile. With MoonBuddy.io I have to look where things are located.
The UI is fine generally speaking but you should install a Light theme. While dark themes are popular for some, there are others who don't like it since it hurts the eyes.
- There are no pages like "privacy policy" "FAQ" "ToS". I think it's important (especially the privacy policy which is a must)
- Favicon missing: I know it's a very little thing
Is it a custom script or?
Good luck with your project

Thats perfect thank you very much! I'll look into rearranging the homepage and adding some more detail to it!
In regards to the activity log - I believe I had wrong directory's selected that should be fixed now!
The basic theme is a purchased one but im hopefully going to revamp it completely bit by bit until its completely different! With the colours i'll add an option to toggle between light and dark. Ill get a privacy policy up as soon as I can total oversight by me! Thank you very much for the feedback its all greatly appreciated!
