I think one key way we can raise awareness is through the implementation of regular, roving events. These could be bimonthly, or even monthly, and would be organised in the first instance by the committee, and then, hopefully, other cachers. Getting the community to feel like they're involved with the GAGB would, I believe, lead to further growth. Of course, this would be difficult to implement (who organises what event?) but we could have an area of the forum for people to request to organise one. Each organiser could even place a GAGB cache to coincide with each event, so that a national GAGB series of caches is established, and people could become competitive in trying to find them all, as has happened with Church Micros.
Obviously, this will take time, but it would certainly raise the awareness and presence of the GAGB, making the community feel like they're involved.
Also, social media could be used to interact with people new to caching. On Twitter, for example, people sometimes tweet about finding their first cache. The GAGB could be the first ones to say congrats, and offer them any help through directing them to the GAGB website. This would introduce new cachers in this instance to the GAGB sooner. I have done this in the past with the CacheWalker Twitter account, and it has increased the number of people following us in addition to our memberbase on the forum.
