How it's measured →0.9%
of downloads still active
At least 1K of 109K lifetime downloads are still running, above its category: the median Uncategorized plugin keeps 0.6%, across 17,774 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Uncategorized plugins, not across the directory. wp.org reports active installs as the bottom of a band, so the real rate is this or higher.
This plugin shipped 10 releases in the last 12 months, and every existing install that updated counted as another download. wp.org publishes no split between first installs and updates, so we show the raw rate rather than guess at one.

wp.org is where the directory puts the plugin for that search. On merit is where it would sit if results were ranked on rating, support and updates, without the install boost. The last column is how far the wp.org position moved, from our first reading in the last 90 days to the latest.

What to do about it
- Your five tags are all earning their place. Each gets you onto page 1 of its own search, so none is worth giving up. “encoded”, “bug tracker” and “relations” (#5, #7 and #11 untagged) would be the next worth testing if a slot frees up.

RPB Chessboard is really a great plugin for any chess related website. I am the Webmaster for my local chess club, and we have just recently redesigned and relaunched our club’s website with WordPress. I use this plugin a lot in my postings and pages, e.g. to show games from our team matches and tournaments, and it looks really good, is very user-friendly and navigable.Also, the developer is very responsive to comments and bug reports. I found a display problem with certain glyphs in a PGN file, and he fixed this problem within one day and made a new release. Great!

This plugin has some great features for a chess-blogger. It works well on my WP blog, and it is easy to understand.

Es ist ziemlich genial. Meistens erzeuge ich die FEN auf lichess und baue sie dann in WordPress ein. Das funktioniert perfekt. Das Gleiche mit PGN. In der Hilfe erfährt man alles, was man erfahren muss. Ein Problem habe ich nur mit dem Worpress-Menü. Wenn es über dem Brett liegt und man mit der Maus drauf kommt, verschwindet es. Was ich mir wünsche: Einen FEN-Import. Ich habe tausende von Stellungen. Manchmal will ich aber noch Pfeile rein machen, Felder hervorheben. Da muss ich immer im eigenen Editor alles neu machen. Ein Import von FEN wäre da super! Was ebenfalls genial wäre: Ein KI-Modus, bei dem man die KI-Stufe vorgeben kann. Das wäre ein Traum. This topic was modified 6 years, 4 months ago by Jan Dembowski.
