Yep. Beside the X button, there's more with a plus sign under it which has almost all the helpful stuff. I noticed you used the ndash in MH, and edittools has the en dash there along with the commonly used wiki codes. It should be really helpful for you :D
It's fine now - I understand what went wrong. The link was w:lostmediaarchive:Alice in Wonderland (1939 David Hall Leica Reel) rather than w:c:lostmediaarchive:Alice in Wonderland (1939 David Hall Leica Reel) so it directed to a nonexistent page on Community Central rather than the Lost Media Archive wikia.
