Develop a new component or use the HelloWorld component to overwrite the original background color.

I want to change the red color of Announcement in the feed, how can I do that?

Solved problem.

I always want to see the menu even when I move the page. Can it be solved?

Thank you :-)

@Zach, well that really depends on the hosting providers and the hardware. But yes in case you face issues please first contact us so we can ensure what is wrong before you make conclusion :)

I wish that upon registration, a membership fee could be paid and OSSN would know who pays and who pays can, who does not pay cannot enter. Is there such an accessory? If there is no add-on, will someone write it?
