GliderReview requires *no login* to submit reviews.

Gliderreview will *never* try to be as exhaustive as Sailplane Directory. We are not even trying to serve the same segment. We are not a "glideopedia", we are a review tool.

GliderReview has a *very* specific focus: help the buyer understand what to buy.
I see no overlap.

If I was the owner of Sailplane Directory I would worry more about Wikipedia: all I know about looking for gliders online is that Wikipedia always come out first.
