I only use this theme because it's up-to-date and works excellently. good work Dev ;))
Got to keep Bootstrap v5.2.3 CSS and JavaScript up to date, you do that and keep the components up to date and it will all work well.

Change theme css look for default.php in your theme css folder

Take a look in locale/ossn.[LANGUAGE_CODE].php files to change it.

how would i go about editing the words Join now to make new friends, create groups, add photos, and much more. on the login screen i have tried to find the file to edit but not finding the area

This is the best theme because people understand it and are used to how it works. I think its a great theme and I am using it ;) keep this one updated my friend great job!

I must admit I have started using this theme and it is the best because it has the latest Bootstrap 5 and you can't beat that ;)

Anyone who wants to change colours, just use the custom css js component and edit front-end js css bits to any colour you want!
