bbpress-0.9.0.5 folder does not show up in the WP admin Plugin Manager (PM) page. I downloaded the bbpress-0.9.0.5.zip. Unzipped and uploaded the folder named "bbpress-0.9.0.5" to the server wp-content\plugins folder. When PM did not show it, I deleted the folder on the server and reuploaded the subfolder folder and contents with the folder name "bbpress" (without the version name. PM still does not show it available to activate. I was not sure which folder to upload to the server since none of my other plugin folders had the version numbers.
