Corporate logo and App logo

Information for the business: We are a social network for nightlife
Industry: Entertainment
Type of logo: Word mark, Letter form
Brand name/slogan in logo: KlubinK
Number of revisions: 2
Ideas for the visual style: Two K's, the first a normal K and the second a reverse K, forming two people joining hands.
Preferred colors: Fluorescent green, black background.
Where the design will be used: In app icon and website.
Extra notes: We are looking for a logo for an app icon and also to be used in the corporate website. The company is a social network for nightlife users. We want the logo to follow the dominant colors of the mobile application and website which are black and fluorescent green. The name of the company is Klubink.
Ideas:
- Play with the two K's. One normal K and one reversed K, forming two people joining hands, ( 'giving 5 to eachother' )
- One K only, with a very thin and attractive design in black and fluorescent green.
- Black background and a simple fluorescent green circle representing the moon, as it is a nightlife company.
-Any good idea is welcome.
