wordpress multisite plugin manager and login issue

Question

i have a blogging system in wordpress

1. i want to active some plugins in my network but users(the blogs owners) cant access to plugin setting in their dashboard, only can use theme
2. another thing that i want to do is that users can login to their weblogs via main site, not to going to their weblogs and do login

edit and solved: the first problem solved via admin menu editor plugin and the second also solved via Redirect Users to Primary Site plugin than i think its not an official plugin for wordpress.

Answer 1

第一个问题通过管理员菜单编辑器插件解决，第二个问题也通过“将用户重定向到主站点”插件解决，我认为这不是Wordpress的官方插件。
