The manager has been here for long time and I'm very certain he knows how to improve and get the best out of the campaign. Repeated suggestion of already considered ideas are not necessary. If he sees anything to work on. I'm sure he will do it. Repeated suggestion is also part of spamming
The campaign has been running smoothly for more than half a year under the same manager. I suppose he/she has already gotten the hang of it despite the fact that he/she hasn't had a single Bitcointalk campaign managed prior to handling this one. It means to say he/she has sufficiently proven that he/she is more than capable of doing it.
However, ideas are always welcome, I believe. After all, that's for the betterment of this overall campaign which has no other goal but to spread BestChange's brand of service. And I guess that's the very reason why the OP has this:
