Basic Advice
Before you start, always read the site guidelines, and any hints and tips. They will steer you in the right direction. Then prepare. Those ads we admire that look spontaneous and fun? The chances are they were actually the result of someone’s hard work. Always use a word processor for your work, then cut and paste it into the site profile or ad (even if answering questions). This builds a document which you can edit and reuse if registering with more then one site, and also gives you a spell/grammar checker to avoid mistakes.
