Hi RP,
some of the Professional Associations are advising their members, quite rightly, to check the benefits of registering etc.
The associations that are on the CNHC website, have, collectively, negotiated an 'early bird' discount for their members, which lasts for 6 months, so effectively, you have 6 months to make up your mind.
As a representative of STO, we are advising our members to register with CNHC, as we have made changes to our own membership to accomodate this. However, we are a single disciplined organisation, so our members will pay the least amount. Not all PA's are in the same position, so will advise their own members accordingly, which is, make sure you are 100% aware of what you are doing before registering.
Your Professional Association is there to ensure you get the best deal, and also to look after your interest.
If the advice is to watch and wait, then do just that, and if it is to join, then likewise.
