<i>Any idea why it wouldn’t show up in the plugins list?</i>
This is how the directory listing of your plugins folder should look:
plugins
– text-control
– – – markdown.php
– – – smartypants.php
– – – textile1.php
– – – textile2.php
– text-control.php
That is, there should be both a folder called “text-control” and a file called “text-control.php”, and both should be in the plugins folder. They should not be inside another folder, like “Text Control Folder”.
Make sure they’re uploaded, then refresh your plugins page.
