Has your friend just given you their username to find them? Struggling to locate them with the search function? Or perhaps you just want a simple way to get to their page...well here it is!
First thing you will need to do is click on your profile pic/icon at the top right of the page and click 'blog'
Then go to your web browser address bar and delete your username (including the @ sign) from there like so:
Then, in the space where your username was, simply insert your friends username (including the @ sign) and press 'enter'/'return' et voila....your friends blog page will now be showing and you can follow them, read their posts, upvote and resteem them!
