I seem to be on level five forever. Not sure how I progress to the next level.
Thanks, but that's already in a comment I put in a reply to cswrawr above. I also mention how you can click & drag the link to your bookmarks toolbar & even that it doesn't open a new tab or window when clicked on...just a dialog box for a quick check.
In case you didn't do it that way....it's the best way IMHO.
Each level takes progressively more XP to move to the next, looking at your profile, you need 72 more Xp to get to level 6.
It might still be an A/B test, but opening someones profile shows their XP for each language . I'm surprised they haven't given it to everyone yet, to be honest.
I think they are actually doing an A/B test to take it away (everyone used to be able to see their progress towards the next level).
I wondered about this too..........which makes the above link even more important. I love having it on my bookmarks toolbar: just click and get a pop-up dialog with the points info, then close it...so quick.
