建议每个版块可以启用独立水印

1、建议每个版块可以启用独立水印，方面绑定二级域名作为子站来运营；
2、建议数据调用的时候多一些筛选功能，比如图片小于多少尺寸的不调用，文字少于多少的不调用，（很多时候模版制作的是图片+标题+摘要，很多网友发一张图片，然后就调取不到文字，只有去手动屏蔽）；
3、还有一点小问题就是如果我某个板块启用了二级域名(bbs2.xxx.com)，但是，比如从首页（bbs.xxx.com） 幻灯片点击进去的话，主题地址还是bbs.xxx.com/******  并不是 bbs2.xxx.com/****** ；

想法不错

支持独立水印

我做了一个简单的，看看能否满足你的要求？
dz现在的应用中心很不好用，我的网站都好几年了，应用中心还是有问题。
